Report
I've used J&b Windows on a number of occasions in the past, and every time they have done an absolutely perfect job. I've had 3 composite doors fitted and they build us a conservatory . We were very very impressed with the result, and their attention to detail is brilliant. Another important note is their aftercare. Whenever I need anything, they are great. I've recommended them to friends and family who are equally as impressed by the work they have done. If I could give 10 stars , I would. Keep up the great work!
